Abstract :
The authors investigate the fibre non-linear effect, self-phase modulation (SPM) and modulation instability (MI), in long distance (>1000 km) dispersion-compensated (DC) conventional optical fibre transmission using numerical simulation and experiments. They compare the results with those in the dispersion-shifted fibre (DSF) transmissions and clarify the remarkable characteristics of DC transmissions, i.e. the characteristic behaviour of the waveform deformation and the absence of the MI. The optimum amount of the dispersion compensation is also discussed, and it is shown that the dispersion window for a transmission thousands of kilometres long is obtained in the average positive dispersion region, and the negative transmitter a-parameter is advantageous
